What do your genes have to do with growing old? Quite a lot. But is it due to the actual DNA, or the way those genes are expressed? KPBS sci-tech reporter Thomas Fudge has more on new research that ...

Much of the phenotypic variation that is observed within and between species is the result of differences in gene regulation: specifically when, where and how much the genes are expressed. Given the ...

What if your food could switch off bad genes? Epinutrition shows how the right nutrients reshape your DNA for better health ...

The natural RNAi mechanism can be directed by either short interfering RNA (siRNA) or microRNA (miRNA). 1 There are four key steps in the RNAi pathway. When miRNA acts as the guide for RNAi, only a ...

A rapidly advancing area of biomedical innovation is shining a spotlight on miR-128-3p, a small yet powerful molecule with the potential to reshape how diseases—especially cancer—are detected, ...

A team led by Cedars-Sinai Health Sciences University investigators has created a faster, cheaper way to determine the genes ...

A new study finds the proteins responsible for controlling which genes are expressed in a genome do more than simply turn a gene on or off. Essentially, each type of protein that interacts with a gene ...

While scientists have known for more than two decades that all cells use a strategy called RNA interference to regulate gene ...

Genetics is the study of genes and how they influence characteristics and health. Through a variety of technological methods, environmental factors, and lifestyle choices, it is possible to alter some ...

Scientists at the MRC Laboratory of Medical Sciences (LMS) have discovered a DNA-based “dimmer switch” that regulates the activity of a critical developmental gene, Cdx2. This work could pave the way ...

Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a particular cell determine what that cell can do. Moreover, each step in the flow of ...
